ACC Hearing Officer Recommends Changes to ACC Rules and
- -------------------------------------------------------
Stranded Cost Orders
- --------------------

     On February 5, 1999, the Hearing Division of the
Arizona Corporation Commission (ACC) issued Proposed Orders
regarding Stranded Cost Recovery and Competition Rules for
Affected Utilities.  TEP must file exceptions to these
Proposed Orders by February 17, 1999.

Stranded Cost Recovery
- ----------------------

     As previously reported, on June 22, 1998, the ACC
adopted an order which outlined two options for stranded
cost recovery: (i) Divestiture/Auction of all generation
assets to determine the amount of stranded costs for 100
percent recovery, or (ii) a Transition Revenues Methodology,
where the Affected Utility would retain generation assets in
a separate affiliate with sufficient revenues necessary to
maintain financial integrity, such as avoiding default under
currently existing financial instruments for a period of ten
years.

     On February 5, 1999, the ACC Hearing Officer issued a
Proposed Opinion and Order (Proposed Order) which recommends
modification of the June order so that divestiture is not
required for 100% stranded cost recovery.  The recommended
order allows each Affected Utility to choose from the
following four options:

1)   Net Revenues Lost Methodology -- Stranded costs would
  be determined by comparing generation revenues with
  competition versus revenues without competition. Stranded
  costs would be separated between regulatory and generation
  assets.  Generation related stranded costs would be
  recovered over a five-year period as follows: (i) standard
  offer customers would pay 100% of their proportionate share
  of stranded costs, and (ii) customers electing to purchase
  energy from competitors would pay through a competitive
  transition charge (CTC) on a declining percentage basis,
  paying 100% in year one, 80% in year two, and decreasing 20%
  each year.  Regulatory assets would be recovered 100% from
  all customers.  Any return on unamortized regulatory assets
  would be reduced by 20% per year over five years following
  the initial five-year period.

2)   Divestiture/Auction Methodology -- Stranded costs would
  be the difference between the market value from sale of non-
  essential generation assets and their book value.  Each
  generation asset would include its portion of appropriate
  regulatory assets.  The Affected Utility would be permitted
  to recover 100% of stranded costs over a ten-year period,
  with no return on the unamortized balance.  All customers
  would be charged either through the standard offer rate or
  through a CTC.

3)   Financial Integrity Methodology -- The Affected Utility
  would maintain financial viability, that is, having revenues
  sufficient to meet minimum financial ratios (similar to the
  previous "Transition Revenues Methodology").  All customers
  would pay their share over a ten-year period either through
  the standard offer rate or through a CTC.

4)   Settlement Methodology -- Some combination of Options
  1, 2, and/or 3, submitted as a settlement option.

     Under the Proposed Order, Affected Utilities may amend
their previously filed stranded cost implementation plans by
March 19, 1999.  TEP's original stranded cost recovery plan,
filed on August 21, 1998, specified divestiture of
generation assets as the preferred method for recovery given
the then available options.
     
     TEP intends to file exceptions to the Proposed Order.
If the Proposed Order on stranded cost recovery is approved,
thereby amending the June 1998 stranded cost order, TEP may
amend its stranded cost recovery proposal.

Retail Electric Competition Rules
- ---------------------------------

     As previously reported, on December 11, 1998 the ACC
adopted the amended Retail Electric Competition Rules
(Rules).  On January 5, 1999, the ACC stayed the Rules
pending additional proceedings to resolve a number of issues
required to implement competition.



     On February 5, 1999, the ACC Hearing Officer issued a
Proposed Opinion and Order recommending changes to the
Rules.  These recommendations include:
     
- --   The date to open an Affected Utility's service
  territory to competition would be set upon the resolution
  its of Stranded Costs and Unbundled Tariffs by final ACC
  order.
- --   If an Affected Utility's service territory is open
  prior to January 1, 2001, the existing phase-in schedule is
  retained, calling for 20 percent of the market to initially
  have access to competitive generation supply.  As part of
  the 20 percent, each Affected Utility is to reserve an
  increasing percentage for residential customers according to
  a set schedule.
- --   Competitive Energy Service Provider affiliates of
  Affected Utilities may not enter another Affected Utility's
  service territory until its own territory is open to
  competition.
- --   The requirement for energy generated from solar sources
  was eliminated, citing it as prohibitively expensive and
  potentially hindering competition in Arizona.
- --   Affected Utilities must file tariffs for unbundled
  noncompetitive services with the ACC by March 19, 1999.

     TEP intends to file exceptions on the Proposed Order.
If the Proposed Order amending the Rules is adopted, it will
be forwarded to the Secretary of State to start the
amendment process.  The Arizona Administrative Procedures
Act requires that the Rules be filed with the Secretary of
State before they can be amended.  We anticipate that the
stay of the Rules would probably remain in effect until
amendments are adopted.


1998 Earnings for UniSource Energy and TEP
- ------------------------------------------

     On February 8, 1999, UniSource Energy Corporation (UNS:
NYSE)  reported  consolidated earnings for  the  year  ended
December  31, 1998.  Net income for 1998 was $28.0  million,
or  $0.87 per share, compared to $83.6 million, or $2.60 per
share,  for  the  same period in 1997. This  difference  was
primarily  due to two items recognized in 1997, but  not  in
1998:  (i)  prior period net operating loss tax benefits  of
$43.4 million; (ii) and reversal of a $6.1 million after-tax
loss provision upon dissolution of an investment subsidiary.

     In  addition,  net  losses related  to  new  businesses
increased  by  $2.7 million, and after-tax interest  expense
increased  $6.4  million due to fixed-rate financings  which
assured   future  interest  payment  stability  and  reduced
refinancing risk.

     UniSource  Energy's unregulated affiliates, held  under
Millennium  Energy Holdings, Inc., incurred a  net  loss  in
1998 of $8.1 million, or $0.25 per share. This compares to a
1997 loss of $5.4 million, or $0.17 per share.

     TEP  recorded  net  income of $41.7  million  in  1998,
compared  with net income of $83.6 million in  1997.   Other
than  the  losses incurred by UniSource Energy's unregulated
subsidiaries, the same factors that explain the year-to-year
change  in  UniSource  Energy's earnings  also  explain  the
change in TEP's earnings.

     In addition to TEP, UniSource Energy's principal
subsidiaries include New Energy Ventures, Inc., a provider
of electric load aggregation, energy management and advisory
services to retail purchasers of electric energy; Advanced
Energy Technologies, Inc., a developer of renewable energy
and distributed generation technologies; Nations Energy
Corp., an independent power developer; Southwest Energy
Solutions; and SWPP Investment Co.
